The results of cartographic modeling of the temperature fields of soils of the land fund of the Novosibirsk region using satellite data obtained by the MODIS/Terra spectroradiometer are considered. The developed cartographic models give a clear idea of the spatial structure of the temperature fields of the soil cover of the Novosibirsk region and the qualitative changes in the temperature regime of soils in different years. According to the data of daytime and nighttime surveys, the peculiarities of the temperature distribution of the soil cover for 2001 and 2010 were established. The values of the average annual temperature of the underlying surface for 2001–2014 were calculated. It is assumed that thermal resources not reflected in the generalization of zonal zoning can be identified on cartographic models. These resources have independent ecological significance and characterize the diversity of landscape, anthropogenic and other types of climate.

The Căpuşului hills are in the Transilvanian depression a trully ”geologycal eocenic golf” with a rich fossilifeuros fauna (Gryphaea eszerházy, G. gigantica, Turrietella imbricataria, Corbula gallica, Cepatia cepacea, Rotularia spirulaea) and also nummulitus species. The pedogenetic cover is constituted by sedimental deposits (clays, marls, limestones, gritsones). Also the pedogentic cover is represented by preluvisoils, luvisoils, eutricambisoils, clay cernozems. The relief characteristics are the Nummulites perforatus, N. fabianii and N. striatus who are the basically substrates from the acrobatically soils. The Transylvanian Depression is considered to be a true "geological eocenical gulf", is remarked through the conservation of a highly rich fossil fauna. Under the geological aspect, on a crystalline base is revealed the whole series of eocenical formations (striped clays, clays and limestone with "numuliti"), oligocenical (carbonatical clays, sands, sand stones and quaternary deposits) (Posea, 1978; Pop, 2001). These sedimentary deposits lay down from the half of the inferior Miocen and finished during the Panonian's end have constituted the parenthal material for the actual pedogenetical cover. A special characteristic of the landscape (with heights of 600-800m), from the outskirts of the Depression (the Huedin Depression, the Paniceni High hills, the Capus and Savadisla Corridor) is the fact that at the surface coating begin to appear "numulits" (Nummulites perforatus, N. fabianii, N. striatus), close to the localities Capusul mic, Leghia, Savadisla, Aghires, Manastireni, Cluj-Calvaria, Vlaha), deposits on which carbonatical soils are formed. If we view this are from the climate's point of view this area belongs to the Dfbk (Koppen) climatical province. The climate is a temperate continental of high hills, with forest. At Cluj-Napoca the average annual precipitations reach 613mm, the average annual temperature has a value of 8.3 degrees C, and the aridity indicator "De Martonne" has the value of 33.7. According to the climate conditions the studied area belongs to the level of oak (Quercus petraea) and the area of mezofilical oaks. (Quercus robur) Generally the areas of forest are mixed with those of pasture or agricultural crops. Because of the diversity of the ecological conditions the soil cover is extremely different, being constitueted of preluvosoils, luvosoils, eutricambosoils, cernosioms, carbonatical soils.

The Way

The plant and soil cover of the dumps of strongly metamorphic rocks of the Gorlovsky anthracite deposit (Novosibirsk region) has been studied. The link between calculated bonite points and the NDVI and SAVI research indices has been revealed. It has been established that the soilecological state of man-made landscapes, composed by highly metamorphic rocks, has a significant impact on the way of surface formation. It is shown that the young planned areas of dumping dense rocks are characterized by an unsatisfactory soil-environmental condition.

Natural Mechanism

By the example of the southern Russian Far East territory, it was stated that a sign of the linear trend of the long-term air temperature variations in the warm and cold periods of the year depended essentially on the soil thermal conductivity. It was shown that the mechanism of the soil temperature fields’ formation was controlled by the Fourier heat condition equation. In this case, the modern anthropogenic loads on the soil cover can only slightly enhance or weaken the natural mechanism of forming the temperature fields of soil and air.

Effective Temperatures

The most important environmental factors for the environment and habitat of plants include temperature. Agro-industrial production requires up-to-date information on the state of thermal resources and the response of plants to global warming within each region. The purpose of the research is to evaluate the state of thermal resources and the dynamics of crop yields in the Northern Steppe of Ukraine. Material for the research was the results of observations of the temperature regime of the AISW Dnipro (1961–1990 and 1991–2018) and data of winter wheat, spring barley, corn, sunflower in stationary experiments on control variants (DPDG “Dnipro”). Statistical data were used to evaluate the data by period: arithmetic mean (M); standard deviation (S); confidence interval (CL0.05) probability (P); repeatability (P × 100 %). Statistical processing was performed using applications in Excel 2003 and Statistica (version 6). Analysis of the thermal regime data showed that in 1991–2018, the average temperature for the year increased by 1.0 °C compared to the climatic norm (1961–1990), by 0.9 °C during the warm and cold periods. vegetation period of early cereals and late crops – by 0.8–1.0 °С. The average rate of increase in the average annual temperature in 1961–2018 was 0.31 ° C/10 years. Between 1991 and 2018, there were 15 cases with temperatures above 9.5 °C, with a recurrence rate of up to 53 %. The last decade (2009–2018) is characterized by a further increase in temperature during the year – by 1.5 ° C, the vegetation of early cere-als – by 1.6 °C, and late crops – by 2.0 °C. It is established that the warming is due to the temperature increase in the cold season – in January, February and March by 1.1,71.7 °C. Positive anomalies occur in July and August (+1.5 ° C). For estimating thermal resources, the important characteristics are the average temperature of the coldest and warmest months of the year. January 10-year average temperatures steadily increased from (-6.5) °C in 1961–1970, to (-4.0) °C in 2011–2018. Their annual variability decreased. The recurrence of high temperature (> -5 °C) in January increased from 34–35 % in 1961–1980 to 73 % in 2011–2018. The average values of July temperatures for 10 annual cycles have steadily increased from 20.8 to 23.0 °C since 1970. The recurrence of temperature> 23.0 °C for 1961–1970 was 2 cases and has increased 2.5 times in recent years. This increases the likelihood of sleepless periods. The positive trend leads to a shift in the dates of the steady transition of the average daily air temperature through 5 °C and the duration of the growing season. Over the last 18 years (2001–2018), it increased by 11–16 days (225 and 209–214). The incidence of such cases increased from 22 % to 44–50 %. At the same time, the increase in the duration of the period with an average daily temperature of ≥10 °C is not statistically significant. The average sums of effective temperatures ≥5 °C over the 10-year cycles in 2011–2018 were 2711 °C, which is 347 °C higher than the base period (1961–1990). Temperature totals increase linearly from 1971 to 2018. However, their recurrence (≥2711) in 2011–2018 sharply increases to 50 %. A close correlation (R2 = 0.75) was established between the duration of the period at ≥5 °C and the sum of effective heat ≥5 °C. A similar trend is typical for effective temperatures at ≥10 °C. The results of the accounting of crops show that for the whole period of observations their average values were: winter wheat (steam) – 4.44 t/ha; spring barley – 2.40 t/ha; corn – 4.32 t/ha; sunflower – 2.15 t/ha. Their distribution was characterized by significant fluctuations due to the variability of weather conditions. However, its maximum levels were noted in the post base period. Against the background of increasing supply of thermal resources in the region, there is an increase in their average yield: steam of winter – by 36 % (3.76 and 5.12 t/ha); spring barley – 24 % (2.14 and 2.65 t/ha ), corn – 11 % (4.14 and 4.59 t/ha), sunflower – 30 % (1.86 and 2.42 t/ha). The probability of forming the optimal yield level of steam winter, spring barley, corn and sunflower (≥4,44; ≥2,40; ≥4,32; ≥2,15 t/ha, respectively, for crops) in the post base period reaches 56–76 % whereas in 1961–1990 it was 25–43 %.

Abstract. Numerical simulations of a bora event, recently occurred in the Adriatic area, are presented. Two reference runs at different horizontal resolution (about 20km and 8km) describe the case. Initial conditions for the atmospheric model integration are obtained from ECMWF analyses. Satellite data are used for comparisons. A further run at horizontal resolution of 8km, using initial satellite sea surface temperatures, is performed to evaluate their impact on the low level wind over the Adriatic Sea. All the simulations are carried out with 50 layers in the vertical. Numerous aspects of the simulations are found to be in agreement with the understanding as well as the observational knowledge of bora distinctive characteristics. Satellite data and model results indicate that a more realistic simulation of the bora wind over the sea is achieved using the model with 8km horizontal resolution and that the low level wind in this case is sensitive, though weakly, to the difference between the used sea surface temperature fields. Simulation results also show that both wind intensity and the area around wind peaks tend to increase when relatively higher sea surface temperatures are used.
